Brian Lich|Last Updated: 3/27/2017

SYNOPSIS

Adds a DHCPv4 option definition on the DHCP server service.

SYNTAX

Add-DhcpServerv4OptionDefinition [-ComputerName <String>] [-Name] <String> [-Description <String>]
 [-OptionId] <UInt32> [-Type] <String> [-MultiValued] [-VendorClass <String>] [-DefaultValue <String[]>]
 [-PassThru] [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf] [-Confirm]
 [<CommonParameters>]

DESCRIPTION

The Add-DhcpServerv4OptionDefinition cmdlet adds a new DHCPv4 option definition on the Dynamic Host Configuration Protocol (DHCP) server service. An option definition must exist before an option value of that type can be configured.

EXAMPLES

Example 1: Add the IPv4 option definition for web proxy auto detection

PS C:\> Add-DhcpServerv4OptionDefinition -Name "WPAD" -OptionId 252 -Type "String"

This example adds the IPv4 option definition for web proxy auto detection (wpad) to the DHCPv4 server service.

Example 2: Add the option definition for the UC identifier for a vendor class

PS C:\> Add-DhcpServerv4OptionDefinition -Name "UCIdentifier" -OptionId 1 -Type "BinaryData" -VendorClass "MS-UC-Client" -Description "UC Identifier"

This example adds the option definition for the Unified Communications (UC) identifier for the vendor class named MS-UC-Client.

PARAMETERS

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.
